A novel, to the best of our knowledge, concept for coherent beam combining is presented based on a simple setup with micro-lens arrays. These standard components are used in a proof-of-principle experiment for both coherent beam splitting and a combination of $5 \times 5$ beams. Here a combination efficiency above 90% is achieved. We call this novel concept “mixed aperture.”

This patent-pending dark field line light has never before been offered to the industry. Combining strategically positioned LED lights on innovative dark strips and newly developed light ray forming optics allows the discovery of previously overlooked flaws in optically clear glass and plastic quality control systems. “Bending” light encircles particles and air pockets creating a glow illuminating the imperfection that can now be seen on a sub-pixel level.
